There seems to be an issue with the grub boot loader. Not sure if we can do anything on this.

EDIT: Ah lol, great that you were able to solve it already :smiley:. The underlying issue seems to be that on upgrade grub was flashed to the wrong drive. Similar to this. It seems that the underlying issue has never really been solved: The ability of the grub install script to reliably detect the correct drive it was booted from.
Hmm, doing some search:

Is it an EFI image or BIOS?

Do you have the ability at early boot to select the OS for some seconds? In this situation, hitting c should bring you into the grub command prompt. If so, it is possible to manually boot from there and then re-install grub: https://archived.forum.manjaro.org/t/solved-grub-problem-grub-rescue-but-the-installation-done-on-external-drive/80188

Else, and probably easier, is to boot form an attached USB drive, or attach the affected broken drive to another system and repair grub from there.

Hi MichaIng . Yes I don’t imagine that I should install the whole system from the beginning :rofl: Next time I should make backup before updating

It’s BIOS . I was not able to boot the system at all . I tried through grub command prompt but also nothing change . The boot from internal hard disk
